Closing arguments are expected this week in Plymouth Superior Court in the trial of Lindsay Clancy, a 36-year-old Massachusetts mother who admitted to strangling her three young children to death in January 2023. Jurors must determine whether she bears criminal responsibility or was incapacitated by postpartum psychosis and bipolar disorder.
The murder trial of Lindsay Clancy reached its final phase in Massachusetts court, with closing arguments anticipated later this week before the case goes to the jury. Clancy, 36, has admitted to strangling her three children—5-year-old Cora, 3-year-old Dawson, and 8-month-old Callan—at their Duxbury home on January 24, 2023. Following the killings, she jumped from a second-story window of the residence, leaving her paralyzed from the waist down.
While the defense acknowledges that Clancy killed her children, attorney Kevin Reddington argues she should not be held criminally responsible due to postpartum psychosis, bipolar disorder, and adverse reactions to prescribed medications. Prosecutors contend that the former labor and delivery nurse planned the attack methodically, deliberately sending her husband, Patrick, out of the house to pick up children’s medicine and family dinner before staging a suicide attempt.
Rebuttal Witnesses Clash Over Mental State and Hallucinations
During the prosecution’s rebuttal case, medical experts offered contrasting interpretations of Clancy’s mental health history. Dr. Gregory Saathoff, a forensic psychiatrist and senior psychiatrist for the FBI’s Behavioral Analysis Unit in Quantico, Virginia, returned to the stand to cast doubt on Clancy’s claims of experiencing psychosis accompanied by command hallucinations.
Saathoff testified that text messages and photographs shared by Clancy in the months prior to the tragedy portrayed a reality vastly different from what she later claimed to be experiencing internally. He also noted inconsistencies in how Clancy described her purported auditory hallucinations to various evaluators.
“This is your last chance.”

Saathoff told jurors it was unusual for a patient to report auditory hallucinations for the very first and last time on the exact evening of the killings. And also, what was very unusual was the fact that the voice stopped with the death of, or the strangling of, her youngest son, Callan,
Saathoff said on the stand, adding that he had never encountered an instance where acting on a command hallucination proved curative
in silencing a voice.
Psychologists Debate Bipolar Diagnosis and Legal Responsibility
Another prosecution rebuttal witness, forensic psychologist Kirk Heilbrun, testified that Clancy retained cognitive control over her actions on the night of the killings and should be held criminally responsible. Heilbrun suggested that Clancy’s actions aligned more closely with altruistic filicide than acute psychosis, noting that she showed signs of peritraumatic dissociation.
Heilbrun added that Clancy’s moral awareness of the wrongfulness of this killing was influenced by her strong desire to die and, if she were dead, not to leave her children behind.
He testified that Clancy described feeling detached during the event, as though she were watching herself act without thinking or decision-making. Yet, he maintained she still demonstrated decision-making capability.
Heilbrun acknowledged struggling to validate a formal bipolar 2 disorder diagnosis because of all the diagnoses in the records and all the symptoms that she experienced. I was having a hard time finding something that looked like it was a manic episode,
Heilbrun told the court, noting that while Clancy experienced periods after childbirth where she felt wonderful and close to her family, those episodes lacked the distinct criteria of hypomania.
A third rebuttal witness, forensic psychiatrist Dr. Avram Mack, similarly testified that when he spoke with Clancy in April, she described feeling miserable and suicidal, but he found no clinical evidence of mania, hypomania, or psychosis.
Defense Case
Before resting its case, the defense called forensic psychiatrist Dr. Phillip Resnick, an expert witness notable for his involvement in the trial of Andrea Yates, who drowned her five children in Texas in 2001 and was ultimately found not guilty by reason of insanity after medical professionals established she suffered from severe postpartum psychosis.
Judge William Sullivan indicated that testimony would conclude following final rebuttal witnesses, with closing arguments slated for later in the week.
